Mononuclear gold(iii) complexes with l-histidine-containing dipeptides: tuning the structural and biological properties by variation of the N-terminal amino acid and counter anion.
Warżajtis B, Glišić BĐ, Savić ND, Pavic A, Vojnovic S, Veselinović A, Nikodinovic-Runic J, Rychlewska U, Djuran MI. Warżajtis B, et al. Dalton Trans. 2017 Feb 21;46(8):2594-2608. doi: 10.1039/c6dt04862e. Dalton Trans. 2017. PMID: 28155927
None of the complexes exerted significant cytotoxic activity; nevertheless complexes that did show selectivity in terms of cancer vs. normal cell lines (2a/b and 4a/b) have been evaluated using zebrafish (Danio rerio) embryos for toxicity and antiangiogenic potentia …

Dinaphthyl tartrates show unusually strong exciton Cotton effects (A = -228 for di-1-naphthyl l-tartrate) due to the coupling of allowed 1B(b) transitions in naphthyl chromophores, despite the acyclic structure and significant distance (over 10 A) between the two chromopho …
